Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
Many thanks to SWLing Post contributor, Mike Hansgen, who shares the following documentary film about the evolution of broadcast radio. This film was actually created for a senior thesis presentation at St. Michael’s College. The film “includes interviews from BBC World Tonight & Joe Reilly (Former President NYS Broadcasters Assn), Empire Broadcasting The Jockey, Clear Channel, WEQX, ESPN, SirusXM, VPR, Skidmore College, & more.”
I have spent the last two months in Las Palmas, Gran Canaria adjacent to the Atlantic Ocean.
I travelled light and didn’t bring my radio/SDR collection with me.
A portable I saw in a local department store caught ny eye, and I ended up buying one from a local electronics retailer which had it on special at €55. It is a Sony ICF-M780SL which as turned out, is something rather special. It is a four band (LW, MW, SW,FM) DSP receiver, with an AM IF (LW, MW,SW) of 45 kHz and an FM IF of 128 kHz.
There’s too much hash in my apartment block to use it at home, but as I am a couple of streets away from the Ocean I intended to use it there.
Problem is there almost as much RF hash at the oceanside as at home. Also the Atlantic breakers crash loudly on the shore, and the wind can howl quite loudly. I did have some limited success and have included a couple of clips.
I discovered a better DX location at a small Plaza a short distance inland from the Ocean. There is an early morning peak for MW TA leading up to about 07:30 UTC (= local time)
The radio is used barefoot in each clip. There is some camera hash.
The Sony ICF-M780SL is a great MW/LW/FM performer. SW propagation has been mediocre and suffers from the RF hash QRN, so difficult to test.
Amazing, Peter! It’s hard for me to believe the reception you had of WFED (Federal News Radio). I listen to that station every time I go through the DC/Baltimore area and I think your reception is just as good. A TA crossing of almost 5,000 km with armchair copy! Quite an accomplishment!
Thank you for sharing your Gran Canaria DX with us. I’m pretty impressed with the Sony ICF-M780SL as well.

Regarding the last couple of posts recently about what affects Space Weather (and HF radio communications), this talk last week from Solar scientist Joan Burkepile of the High Altitude Observatory discusses what causes Radiation storms from Coronal Mass Ejections. She makes it interesting from a physics point of view. And as we understand the sun better, we also learn more about how the rest of the universe behaves.
Many thanks to Jon Hudson at SDRplay who produced the following excellent instructional video about setting up SDR-Console V3 for remote use. Jon writes:
For SDR Console users, this video guide shows you how to access other people’s SDRs and how to add your own.
If you are wanting to add your own SDR for remote use, there are a couple of things to be careful with:
Be careful when plugging multiple SDRs into a single USB2 socket to make sure there’s enough power – for multiple SDRs, you may need a powered hub ( like this: http://amzn.to/2oa84kM) [or this in North America].
Once you are up and running – please go to http://www.sdrspace.com/Version-3 and view your listing – if there is a yellow triangle, then you are not accessible outside your own firewall – attention is needed! Just because you can access it on your own LAN doesn’t mean it’s accessible via the internet!!! This is the most common area to have problems – double check your router’s port forwarding settings are correct (default port 50101 TCP).
Many thanks to SWLing Post contributor, Ivan Cholakov, who shares the following video where he compares the SDRplay RSP1A and the AirSpy HF+ software defined radios on shortwave and mediumwave:
Welcome to our 20th episode! In this revamped show we conclude our look at innovative amateur radio products from Hamfest 2017, and Bob goes back to basics with an overview of setting up an inexpensive SDR dongle.
We have two great prizes to give away in our free-to-enter draw. An RSP1A SDR receiver from SDRplay and a copy of the best-selling book ‘SDR’ from the RSGB. Plus we look back at the past four years of topics covered by the TX Factor team. We hope you enjoy it! http://www.txfactor.co.uk
